A NiO x -graphene oxide (NiO x -GO) hybrid has been prepared by a simple solution-processed method and was used as hole-extraction material in perovskite solar cells with either gold or carbon as back contact electrode. The impact of GO content on the optoelectronic behavior of NiO x and the photovoltaic performance of the fabricated devices has been studied. Thus, GO incorporation showed a significant improvement in the performance of NiO x -based devices. The best attained efficiency was 13.3%, and it was 45% higher than that with pure NiO x . This is attributed to a significant improvement in the hole extraction, recombination resistance, and energy-level matching in comparison to pure NiO x . In addition, NiO x -GO/Au-based perovskite solar cell devices showed a negligible hysteresis effect and high reliability and repeatability. When carbon was used as back contact electrode, the obtained efficiencies were lower, but it leaves space for improvement. Devices based on inorganic hole transporters NiO x or NiO x -GO demonstrated higher stability in ambient air compared to a standard cell based on spiro-OMeTAD.

使用无机空穴提取组分构建钙钛矿太阳能电池。
通过简单的固溶处理方法制备了NiO x-氧化石墨烯（NiO x -GO）杂化物，并用作钙钛矿型太阳能电池中以金或碳为背接触电极的空穴提取材料。研究了GO含量对NiO x光电行为和所制造器件的光伏性能的影响。因此，GO掺入显示出基于NiO x的器件性能的显着改善。最佳获得效率为13.3％，比纯NiO x高出45％。与纯NiO x相比，这归因于空穴提取，抗复合性和能级匹配方面的显着改善。另外，基于NiO x -GO / Au的钙钛矿太阳能电池器件显示出可忽略的滞后效应以及高可靠性和可重复性。当使用碳作为背接触电极时，获得的效率较低，但是留有改进的空间。与基于spiro-OMeTAD的标准电池相比，基于无机空穴传输器NiO x或NiO x -GO的设备在环境空气中表现出更高的稳定性。
